first of all i'm going to die anyway my 8yr old daughter is a whizz at the pump track and i'm getting cold and bored the fact that i'm old and can't learn new tricks will be a painful problem.....
so knocking up an ss from old parts - Q: using a middle ring/short bolts OCD is ok - does the cog have to sit outside the spider - chainline looks no good looks but like will fit inside ok?? can't think of any reason not to do it - can you?
